TS-File not seekable
Locked
 
|
I’ve made some test to finish the pipe: Direct call of ‘g_main_loop_quit (loop)’
ore parsing message with ‘gst_element_send_event (dvb_pipe,
gst_event_new_eos())’ and handle the loop_quit in the message loop
function, but all with the same result. My question is now: Where is the different between
gst-launch and my own program in the ts-file results? What do gst-launch more
then I do? If someone could help me, I will be very happy! Thanks a lot Bernhard --------------------------------------------------------------------- Hi @ all, I’ve an issue with my own program using
dvbbasebin: The pipe: gst-launch-1.0 dvbbasebin adapter=1
frequency=12544000 program-numbers="17501" polarity="h"
symbol-rate=22000 ! queue ! tsparse ! filesink location=test_ts.mpg Results a file that has no problem with seeking But my own program: ************************************************************************** #include

Hi Bernhard,
What do you mean by "different results" and "problem with seeking"? Could you be more specific? Does your program produce non empty file? Why do you need tsparse if you writing to a file? Are you going to handle some messages from tsparse? In the first instance you don't have to force EOS in your app. Just stop your program on the command line by pressing Ctrl+C and the default signal handler will do the job. You can improve it later. You can learn more about your program behaviour if you set GST_DEBUG variable when running it, e. g.: GST_DEBUG=4 ./your-app See gst-launch-1.0 manual to learn more about debugging levels. I'd recommend making your app simpler so you can evolve it later. Use gst_parse_launch() instead of gst_element_factory_make(). Less code, less oportunity to make a mistake and you can always refer to any element in the pipe by its name (use 'name' property): GError *error; GstElement *dvb_pipe = gst_parse_launch ("dvbbasebin name=dvb" " ! queue ! tsparse " " ! filesink qos=TRUE", &error); if (!dvb_pipe) { g_printerr ("Failed to create the pipeline: %s\n", error ? error->message : "(unknown error)"); return FALSE; } dvb_bus = gst_pipeline_get_bus (GST_PIPELINE (dvb_pipe)); gst_bus_add_watch (dvb_bus, dvb_bus_call, NULL); gst_object_unref (dvb_bus); Return gboolean instead of int unless you have a good reason to return int. You can use g_object_set() to set multiple properties: dvb_source = gst_bin_get_by_name (GST_BIN (dvb_pipe), "dvb"); g_object_set (G_OBJECT (dvb_source), "adapter", atoi(argv[3]), "frontend", atoi(argv[6]), "frequency", atoi(freq), "program_numbers", argv[7], "polarity", argv[9], "symbol-rate", atoi(argv[5]), NULL); Cheers, Kris On 30/11/12 08:03, Bernhard Graaf wrote: > I've made some test to finish the pipe: > > Direct call of 'g_main_loop_quit (loop)' ore parsing message with > 'gst_element_send_event (dvb_pipe, gst_event_new_eos())' and handle the > loop_quit in the message loop function, but all with the same result. > > My question is now: Where is the different between gst-launch and my own > program in the ts-file results?

Hi Kris,
Thanks a lot for your answer. I'll check it with using 'gst_parse_launch'. That's a good idea. For the problem I have: The timing information of the TS-File seams to be corrupt, because in a second program (using tsdemux or playbin) the playback is hanging after try to seek using gst_element_seek. If I open another file (generated by gst-launch) its OK. Therefore I believe that there is a problem with the file not with the seeking program. Thanks again. I will follow your idea and give you the result of my test.

Hi Kris,
Don't work as expected. The pipe with using 'gst_parse_launch' is running well, but the result is the same. Normal playing not a problem but seeking has a problem. In the meantime I've got an error message: 'GStreamer-CRITICAL **: gst_segment_do_seek: assertion `segment->format == format' failed'. If I do the same seeking with other files (f.e. with 'gst-launch' on command line), I have no problems with that. So the ts-file has a problem. I've also tried to reduce the pipe (dvbbasebin ! queue ! filesink) without any additional parameter, but the result is the same. I've no idea where to search to fix it. I've also no idea where the different is between command line and gst_parse_launch. There should be a different because of different results. Any additional ideas? Could the DVB-Card be the problem (Conexant CX24123/CX24109 Chipset)? You make me happy if you have any ideas to fix it!

Hi Bernhard,
You mentioned another program using tsdemux. AFAIK there were some fixes around these issues in tsdemux and they're included in GStreamer-1.0.3. Could you try it?

If gst-launch-1.0 ... works differently than gst_parse_launch() linked against libgstreamer-1.0, that's rather unexpected I would say, especially in a case like this where the extra send_event(EOS) shouldn't really make a difference. Note that 'gst-launch' == gst-launch-0.10 not gst-launch-1.0. Another thing to check is whether you actually configure the properties on the dvb source correctly in your program. Perhaps you got the argument order on the command line wrong, or a property type, or somesuch. What you could do is add a GST_MESSAGE_ASYNC_DONE case block to your message handler, in which you call case GST_MESSAGE_ASYNC_DONE: GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS (GST_BIN (pipeline), GST_DEBUG_GRAPH_SHOW_ALL, "pipeline-dump.dot"); break; in your code and then take a snapshot and create an image of the setup as described here: http://gstreamer.freedesktop.org/wiki/DumpingPipelineGraphs and here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#GST-DEBUG-BIN-TO-DOT-FILE:CAPS Cheers -Tim > -----Ursprüngliche Nachricht----- > Von: gstreamer-devel-bounces+bernhard.graaf=[hidden email] > [mailto:gstreamer-devel-bounces+bernhard.graaf=[hidden email]] > Im Auftrag von Bernhard Graaf > Gesendet: Freitag, 30.

In reply to this post by Krzysztof Konopko
Hello Kris,
I'm using already Version 1.0.3 and I've seen the bugreport regarding tsdemux. But my problem is more the file out of dvbbasebin ! filesink (there is no tsdemux used). I'm more and more believe that I have a hardware problem, because if there is a basic fault, more developers will have the same problem. So it's something I have different to them. If you tell me, that there is no basic fault in my code, I've try to check on other battlefields. I thank you very much for your time and inform you about the results!

Hi Tim,
Great idea. I'll check it and come back with results.

If gst-launch-1.0 ... works differently than gst_parse_launch() linked against libgstreamer-1.0, that's rather unexpected I would say, especially in a case like this where the extra send_event(EOS) shouldn't really make a difference. Note that 'gst-launch' == gst-launch-0.10 not gst-launch-1.0. Another thing to check is whether you actually configure the properties on the dvb source correctly in your program. Perhaps you got the argument order on the command line wrong, or a property type, or somesuch. What you could do is add a GST_MESSAGE_ASYNC_DONE case block to your message handler, in which you call case GST_MESSAGE_ASYNC_DONE: GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS (GST_BIN (pipeline), GST_DEBUG_GRAPH_SHOW_ALL, "pipeline-dump.dot"); break; in your code and then take a snapshot and create an image of the setup as described here: http://gstreamer.freedesktop.org/wiki/DumpingPipelineGraphs and here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstr eamer-GstInfo.html#GST-DEBUG-BIN-TO-DOT-FILE:CAPS Cheers -Tim > -----Ursprüngliche Nachricht----- > Von: gstreamer-devel-bounces+bernhard.graaf=[hidden email] > [mailto:gstreamer-devel-bounces+bernhard.graaf=[hidden email]] > Im Auftrag von Bernhard Graaf > Gesendet: Freitag, 30.

Dear all, Appart from include the "-e" option to de pipeline to insert a EOS signal when you perform the ctrl+c, you can try to close properly the file.
/* Now set to playing and iterate. */ g_print ("Setting to PLAYING\n"); gst_element_set_state (pipeline, GST_STATE_PLAYING); g_print ("Running\n");
:
/* clean up nicely */ gst_element_send_event (pipeline, gst_event_new_eos ()); /* wait for EOS message on the pipeline bus */ msg = gst_bus_timed_pop_filtered (GST_ELEMENT_BUS (pipeline), GST_MESSAGE_EOS | GST_MESSAGE_ERROR, GST_CLOCK_TIME_NONE); /* should check if we got an error message here or an eos */ gst_element_set_state (pipeline, GST_STATE_NULL); g_print ("Deleting pipeline\n");
gst_object_unref (GST_OBJECT (pipeline)); Best, Angel 2012/11/30 Bernhard Graaf <[hidden email]> Hi Tim, _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
